Picks up where Part 2 climaxed a la cliffhanger. Stuck in 1955, time-traveling hero Marty frantically searches for Doc Part 1 so he can return to 1985. Instead, he finds himself in the Wild West circa 1885, trying to save Doc's life. Plot is related to earlier BTTFs, so first time viewers might be confused. For those who've seen previous incarnations, the clever interconnections are really nifty. Nearly matches the original for excitement and offers some snazzy new special effects. Supposedly the last installment, though don't be surprised if another sequel follows. The complete trilogy is available as a boxed set.
